ADJUSTABLE CLAMP non nusnnnr rns AND THELIKE.

Application filed September 12,1922. Serial No. .587,718.

To (ZZZ 10. mm it may concern.

lie it known that I, ROBERT JAMES HAM- :eonn, a subject of the King of Great Britain and Ireland, residin' at London, in the county of London, ngland, have invented new and useful Improvements in or .telating to Adjustable Clamps for Rubber Pipes and'the like, for which I have filed an application in Great Britain,

on the 5th May, 1922, of which the following is a specification.

This invention relates to adjustable clips for india-rubber and like pipes and indiarubber and like flexibly covered electric conductors, cables and the like.

The primary object of the invention is to improve the means for clamping flexible pipes on to their connections.

A further object is to improve the means for clamping flexibly covered electric conductors and the like.

A still further object is to facilitate the fixing and removal of the said clips.

Yet another object is to enable the said clips to be attached to a wall or the like so as to fix the said pipes or conductors in position.

Another object is to provide a clip which gives a powerful distributed pressure over the surface of the flexible pipe or covering.

Other objects will be set forth in the body of the specification.

According to this invention, a clip for india-rubber and like resilient pipes or flexibly covered electric conductors, or cables is provided with a loop member adapted to be placed around the pipe whilst a bridge piece, which carries a member for engaging the pipe, is provided with heads adapted to engage the ends of the loop so as to prevent disengagement when the clip is in the operating position. The loop member is preferably formed as a U shaped band and is slightly flexible with holes in the ends and the sides of the said holes converge towards the end, or are formed in the shape of a key-hole with the narrow portion towards the ends to permit the en larged heads on the bridge piece to be passed through the wide portion of the said holes and, when slipped up into the narrow portion to prevent the disengagement of the bridge piece from the band. The loop member may be formed as a double wire loop adapted to engage the ends of the bridge cording to. the

piece, orit-may be formed as a single wire loop having-the ends formed with eyes.

A practical example of construction acinvention isdescribed with reference to the accompanying 1 figures wherein: e V v Figure 1. is an end view showing the clip in position on a flexible pipe.

Figure2. is aplan of Figure 1.

Figure3. is a side view of Figure 1.

:Figure 4. is an end View showing the clipinposition on an electric insulated cable attached toawall.

Figure 5. is a side elevation of a modified clip having a double wire loop.

A U shaped band or loop a is formed of sheet metal and is provided with holes 6 of truncated triangular shape with the sides a converging towards the ends of the band a. The bridge piece d, provided with an adjustable centre screw e to which the saddle piece 7 is swivelly attached, is in serted in the said holes and is provided adjacent its ends with recesses g to permit it being slid into the narrow portion of the said holes thus preventing disengagement from the sides of the hands when pressure is applied to the bridge piece. The recesses 9 form in effect enlarged heads h on the ends of the bridge piece.

The flexible pipe or hose is inserted in the U shaped band at below the saddle piece f so that the circumference of the pipe is almost entirely enclosed, and the pipe is securely clamped to its connection without possibility of leakage or distortion. A quick release of the clip may be obtained by a few turns of the central screw 6 thus releasing the bridge piece (Z which may then be pressed down on one side to the wide portion of one of the holes 6 when the U shaped band may be disengaged from the bridge piece. V V

The'U shaped band is preferably sufliciently flexible to permit thesides to spring inwards slightly and grip the pipe or hose on the side when pressure is applied to the saddle piece.

In the modification shown in Figure 4 the clip is shown applied to flexibly covered conductors to enable the conductors to be attached to a wall or the like, or to prevent the ends of the insulation from unravelling.

In the modification shown in Figure 5 the U shaped member is formed as a double the ends of which'are engaged g end'ofthe said wire loop 2', by the ends of the bridge pieced.

What I claim is.

1. A clip for 'india-rubber and like pipes and covered cables and conductors comprising a U shaped band having hole in each" end with the outer ends of the said hole narrower than the inner'end, abridge piece,

an enlarged head on each end of the said bridge piece adapted to pass thrdughlhe wider portion of the c'orres'pondi'r-ig'hole'in the band andwhen slipped u p'f'into the narrower portion to reventdisen agement from the band, ascrw' said bridge 7 pier'ze, "'and of the bridge piece threading through a saddle piece swivelly connected to *said screw.

2. A clip for india-rnbber and like pipes and covered cables and conductors comprisingfa U shaped "band having "a key-shaped hole in each end witlrthe'narrower portion of the said holene'arenthe end of the band than the wider portion, a bridge piecefan enlarged head on each bridge piece-adapted to pass through the wider sponding hole the band, a screw threading throiigh said bridge pi'ece, and a saddle piece swivelly connected tosaid screw.

3. A clip for india-rubber and like pip'es and covered I cables and conductors comprising a loop member having a hole in each end, a bridge piece, sions of" said bridge piece engaging said holes, a screw turning said" s'crevv,' a "saddle piece, a V shoulder on "s'aidscrefw acting as a seating, to
